testo 312-4 - Differential pressure measuring instrument
订货号 0632 0327
Gas-tightness and serviceability test by pressure drop on gas pipes according to DVGW-TRGI 2008
Load test on gas pipes according to DVGW-TRGI 2008 with the help of the high pressure probe
Pressure tests on drinking water pipes with water using the high-pressure probe according to DIN 1988 (TRWI) as well as with air accoding to the ZVSHK information sheet
Pressure test on waste water pipes according to DIN EN 1610
You can carry out all the necessary tests on gas heating systems as well as water and gas pipes with the testo 312-4 electronic differential pressure measuring instrument. Preset measuring processes, for example for load and tightness tests as well as serviceability testing on gas pipes, provide you with ideal support for your work.
产品描述
A variety of directives describe the tests which have to be
carried out before commissioning water and gas pipes. The testo 312-4
differential pressure measuring instrument offers measuring processes
for load and tightness tests as well as serviceability tests on gas
pipes using air. It also enables the checking of static gas and gas flow
pressures, as well as the nozzle pressure setting on gas burners or
boilers.
These measurements are possible with the testo 312-4 differential pressure measuring instrument
Practical features of the differential pressure measuring instrument
The
testo 312-4 pressure measuring instrument offers a high level of
operating convenience in order for you to carry out pressure measurement
efficiently – for instance through preset measuring processes or the
clear presentation of readings on the large display. The testo fast
printer, which can be ordered as an extra, means you can produce
measurement data printouts directly on site. The easyheat PC software is
available to you as an option for data transfer and evaluation.
Furthermore, probes which are also available for various measuring tasks
can be attached to the differential pressure measuring instrument (e.g.
high-pressure probe or thermocouple probe for temperature measurement).
